What is 1 5/8- 3/8 Express the answer in simplest form

Naddika [18.5K]

1 5/8 - 3/8 = 1 1/4

Subtract the numerators because the common denominators are the same and leave the whole number to make 1 2/8. To simplify it you divide it by 2 because that's the highest number that can go into both numerator and denominator to make is 1 1/4.

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t

ehidna [41]

Answer:

The probability that more than a third of the buyers would prefer brown is 0.8491.

Step-by-step explanation:

This is binomial problem with n=15 and p=0.50.

The binomial formula of probaility is:

P(X=x)= $\frac{n!}{x!(n-x)!} p^{x} (1-p)^{n-x}$

More than a third of the buyers: 15÷3=5

We have to find P(x>5).

P(x>5) = 1 - P(x≤5) = 1 - P(x=0) - P(x=1) - P(x=2) - P(x=3) - P(x=4) - P(x=5)

P(x=0)= $\frac{15!}{0!15!} (0.5)^{0} (1-0.5)^{15}$ =0.00003

P(x=1)= $\frac{15!}{1!14!} (0.5)^{1} (1-0.5)^{14}$ =0.00046

P(x=2)= $\frac{15!}{2!13!} (0.5)^{2} (1-0.5)^{13}$ =0.00320

P(x=3)= $\frac{15!}{3!12!} (0.5)^{3} (1-0.5)^{12}$ =0.01389

P(x=4)= $\frac{15!}{4!11!} (0.5)^{4} (1-0.5)^{11}$ =0.04165

P(x=5)= $\frac{15!}{5!10!} (0.5)^{5} (1-0.5)^{10}$ =0.09164

P(x>5) = 1 - P(x≤5)= 1- 0.00003 - 0.00046 - 0.00320 - 0.01389 - 0.04165 - 0.09164 = 0.8491
